Occurrence of Metacaligus rufus (Wilson, 1908) (Copepoda, Caligidae) parasitizing the cownose ray Rhinoptera bonasus (Mitchill, 1815) (Elasmobranchii, Myliobatidae) in Brazil

Reprodution of the Cownose ray, Rhinoptera bonasus Mitchill, 1815 (Elasmobranchii, Rhinopteridae), in captivity and newborn care.

Feeding biomechanics of the cownose ray, Rhinoptera bonasus, over ontogeny.

Growth affects the performance of structure, so the pattern of growth must influence the role of a structure and an organism. Because animal performance is linked to morphological specialization, ontogenetic change in size may influence an organism's biological role. High bite force generation is presumably selected for in durophagous taxa. Therefore, these animals provide an excellent study sy...

Anisakidae and Raphidascarididae larvae parasitizing Selene setapinnis (Mitchill, 1815) in the State of Rio de Janeiro, Brazil.

Between February and August, 2012, thirty specimens of Atlantic moonfish, Selene setapinnis, were purchased in local markets in Niterói, State of Rio de Janeiro, Brazil, with the aim of analyzing the presence of anisakid nematodes, establishing their rates of parasitism and infection sites, due to importance in the sanitary inspection. A total of sixty nematode larvae, belonging to at least two...

Occurrence of Clavellisa ilishae (Copepoda: Lernaeopodidae) parasitizing herrings (Actinopterygii: Clupeidae) in Brazil.

The lernaeopodids are highly specialized copepods which are widely distributed worldwide. In this paper the first record of Clavellisa ilishae Pillai, 1962 in the Neotropical region is documented parasitizing Sardinella brasiliensis from coastal zone of Rio de Janeiro, Brasil.

First record of Caligus mutabilis (Copepoda: Caligidae), in sea-farmed Mycteroperca microlepis (Perciformes: Serranidae) in Brazil.

Sea lice (copepods) are widespread pathogens in marine teleost cultivation around the world. The sea louse Caligus mutabilis Wilson, 1905, is recorded here for the first time in sea-farmed gag grouper, Mycteroperca microlepis, in Brazil.
